Reply to the letter to the editor ‘How much evidence isn't in evidence-based guidelines?’ by Johnson et al.
ABSTRACT ESMO produces pan-European, multidisciplinary, peer-reviewed and updatable guidelines with global impact on current clinical practice, with the intention of providing the practising health professional in cancer care with an easy to use, evidence-based tool for optimal patient management. Levels of evidence and strength of recommendation metrics are provided. In the Dyspnoea ESMO CPG, we strove to fulfill these targets, though we accept any productive criticism that will contribute to the improvement of the product.
